Application area and features
- Universal KNX actuator with 8 freely configurable output channels for switch, shutter (AC/DC), fan coil, or valve control.
- KNX Secure capable, configured via ETS5 or higher.
- Switch outputs: time functions (on/off delay, flashing, staircase lighting), 8 scenes, logic (AND, OR, XOR, GATE), status response, forced operation, operation-hours counter.
- Shutter AC/DC outputs: up/down, position 0–100%, louvre adjustment, 8 scenes, automatic sun protection, safety function, two modes (Venetian Blind / Shutter).
- Fan coil outputs: up to 3-level fan speed, step-switch and steering-switch modes, automatic, manual and forced operation.
- Valve outputs: continuous (3-point), PWM and 2-point switching; valve-curve correction and automatic cleaning for continuous valves.
- Manual operation buttons on the device for commissioning and engineering debugging.
- Configurable behavior on bus voltage failure and recovery.
- Powered directly via the KNX bus, no additional supply voltage required.
